The Beta Testers have to sign NON disclosure agreements while the product is undergoing testing. When it is out of Beta Testing and begins roll-out, they can talk about it.
This testing needs to end quickly. Next to CDV, request for ??? HD, The TiVo software upgrade is the most requested Item to all Comcast Call Centers.
But due to the CDV Major Roll-out that began on Sept. 01, 2006, Everything else is secondary for right now.
Even with the non-disclosure i'm surprised pictures and/or comments on the beta Tivo software haven't leaked. It seems like this always happens with other high demand software currently in beta.
